Hello,
I am planning to build aleph amp and preamp more ( I have tries some already), in order to make it better, I have some doubts.
First for Aleph P1.7, Does it need separate power supply for each channel ( service manual show one power supply feed both channel). Does it be worthwhile to do that? compare to more cost added.
Second point, for mosfet matching, beside the current used. I curious that, do we need regulate power supply to do this job or not? Does a little voltage swing affect the Vgs value that we can measure from each mosfet?
I have tried to match the mosfet following the procedure in passdiy site, but still some deviation between each matched. Do I miss some point to make it perfect match.
Thank you for Answer
